TROUBLESHOOTING AND MAINTENANCE
Inspect and tighten all parts each time the weight system is used. Replace any worn parts immediately. The weight system can be cleaned using a damp cloth and mild non-abrasive detergent. Do not use solvents.
TIGHTENING THE CABLES
Woven cable, the type of cable used on the weight system, can stretch slightly when it is first used. If there is slack in the cables before resistance is felt, the cables should be tightened.
Slack can be removed by moving the 3 1/2” Pulley (15) to the lower hole in the Long “U”-bracket (57). Remove the 3/8” Nylon Locknut (21) and the 3/8” x 2” Bolt (12) from the Cable Trap (66), Pulley, and “U”- bracket. Re-attach the Pulley and Cable Trap. Make sure that the Cable Trap is positioned to hold the Cable in place, and that the Cable and Pulley move smoothly.
Additional slack can be removed from the cables by tightening the 1/4” Nylon Locknuts (2) at the end of the Long Cable (23) and at the end of the Short Cable (58). To do this, you may need to remove the Small “U”- bracket (67) from the Weight Tube (63) or remove the 3 1/2” Pulley (15) from the Long “U”- bracket (57). Make sure that the cables are not too tight, or the Top Weight (76) will be lifted off the weight stack.
Note: If a cable tends to slip off the pulleys often, the cable may have become twisted. Remove the cable and reinstall it.
If the cables need to be replaced, see ORDERING REPLACEMENT PARTS on the back cover of this manual.
CABLE DIAGRAM
The cable diagram below shows the proper routing of the Long Cable (23) and the Short Cable (58). Use the diagram to make sure that the two Cables and the cable traps have been assembled correctly. If the Cables have not been correctly routed, the weight system will not function properly, and damage may occur. The numbers show the correct route for each Cable; the starting and ending points of each Cable are labeled. Make sure that the cable traps do not touch or bind the Cables.
